DEVICE FORMING STRUCTURE OF GAS AND FLUID FLOW IN WELLS Russian patent published in 2004 - IPC

FIELD: production of gas and fluid mixtures, specifically, of live crude. SUBSTANCE: invention can find use in wells with natural flowing of producing object or with artificial supply of gas for gas lift of fluid. Device includes gas lifting string of pipes which houses members forming structure of gas and fluid flow. These members come in the form of working media-beads which number exceeds one with relation d_b/dinst

≤0,9, where d_b is maximum diameter or radial size of beads; dinst is internal diameter of lifting string. Beads are freely threaded on to bearing suspension in the form of rope or rod assembly and are distributed over length of lifting string for radial or axial movement. Axial movement of beads is regulated within limits of intervals of arrangement of limiters. EFFECT: enhanced efficiency of device, reduced outburst of accompanying gas and flow rate of pumped gas. 2 cl, 3 dwg
